I'm thinking of possibly trading my 65 Dodge dart GT blown 440 for a A body or b-body four-speed.

So why the potential swap? I realize you're not committed but why a swap now? I'd get your boost/ignition controller and enjoy the car for a bit. I've had my 68 for about 27 years and have started to entertain the thought of selling it. Don't have room for a 3rd car.
Well I've been working on cars for a lot of years. That one there was a particularly intricate and putting that big block in place. I know other guys have done it over the years but I wanted to do it without cutting anything up. I wanted to retain the factory shock towers and everything like that and to make everything work and I did and I'm just entertaining a thought. It would be nice to have something that I could just clean on and go out and drive and enjoy which that is a head turner and it does do it but I'm always doing something to it to make it a little bit better. A little bit different I don't know. Just thinking a different way. No real reason. How's that? lol no but it was a job to put that in there. Believe they're not. Everything was made to fit. There was nothing you could really go by to make the job any easier.
